, 'Be it known, that I, HENRY Rionannso N,"

' 5.State of Illinois, have invented certain new and useful 'In'i rovements in Bed-Bottom Fabrics, of whic the-following is a specifica- 1 My invention -.relates-- to bed bottom fabrics, and pertains more especially tothat class or type of fabrics which are made up of interconnected bent wire units." 1%

Among the principalobjectsof theai'nven tion are to lessen the cost of manufacture by eliminating the rings, apertured plates, conmeeting clips, and-similar adjunctive devices zit/present extensively employed in associationwith and forconnecting the bentvwire units; and toim rove the appearance and serviceability of t e fabricthroug'h the avoidance of What is known as diagonal tension, and also by -m'eans' of'a construction which prevents partial dis lacement of the individual units relative to each other and the plane of the fabric dire to their interlinked connection,- and, while preserving the interlinked connection, permits the individual unitsto occupytheir normal positions substantially and coincident with the plane of the fabric, thuspresenting a substantially level and fiat and uniform Wearing surface 'thefab'ric as a Whole. Theseseveralobjects" are attained preferablg stmction qfi diamond-s ap'ed bent wire unit, and a 8]);60131 manner of connectingsuch units longitudinal and transverserows, the units being l preferably provided withins teg'lnlhoolis an eyes at their opposite ends, respectively-,whereby they are readily con- 40 nested up to form thelongitudinal strands; and the sides of the units atthe angles formed by their 0 positely inclined portlons beings laterally-o set so as to accommodate the interlinking of the sideswith adjacent units without producing an upsetting or distortion of the engaged sidesre ativ'ely to'the plane of the fabric. l e p My invention willbe more clearl understood when Tconsidered' inconnectmn with 6 the accompanying drawing, in whieh' Figured ,is a fra mental-y plan view of n'ay' improved bed-bot om {fabric;,;and Fig.2 is an edgeview of the same-in cross-section 555F336 erring totne drewnigw desi te-1 w Spebitlcation of Letters lBatent.

the side rail and 6 the end rail of an ordinary bed frame,- saidrails being preferably in the form of angle bars rigidly united at the cornejrs by'bolps 7 and nuts. 8. I

The fabric of'the bed-bottom is composed 60 of a series 30f units each formed of a stri of 'wire bent to present outwardly bowed sides convergent at both ends toward the longitudinal" median line or axis of the unit,said units being disposed in straight longitudinal 5 and transverse rows throughout the fabric.

In the preferred forrnof unit herein shown the wire is bent to form a diamond-shaped [body-portion, indicated by 9, with an integral eye 10 formed atone end of the unit and 7 an integral hook 11 formed at the opposite end, said hook beingproduced 'by bendi v inwardly of the unit the two convergent eiid portions of the sides of the unit at the end of v the latter opposite to the eye 10. Asabove 7'5 stated theunits are disposed in straight longitudinal strands, or with their 'longitw dinal axes in alinernent, being united b simply engagin ,the hook I} of one unit wit theeye 10 oft e'next unit; and the several longitudinal rows or strands are connected laterally b directly inter-linking the adjacent sides of t e units in the same transverse rows, as indicated at12 The two sides of theunit being disconnected at its 'hooked"g5 end, the units may be readil;

.con neeted ,up in the manner described an showndurin the operation of assembling the fabric,- an

Separ e uxiliary connecting links or cllpg g such'as are commonly and extensively use r in bed-bottom fabrics at present invogue. In order to secure a smooth and, substantially level upper or wearing surface, the eyes- 10 are preferably slightly offset laterally of the plane of the fabric as shown at 13 (Fig.

.-2) while the sides of the units atthe points where they are laterall interlinked are also laterally ofiset relative y to the plane 'of; the i At the longitudinal edges of the -fabric,' half units 9'} are employe "in order to, 170- .duce straight longitudinal edges, said alf units be'' the latera y adjacent row of whole units in the manner and by' the means already described.

connected to each other and to ,To .afiord increased elasticity, lithe fabric I at eitheror both ends maybe connected with 'fthe end rail through theginterposition" of; 1h

helical springs 15 having at their outer ends hooks 16 that engage apertures 17 formed'in and through saidrail, all as usual in this type of bed-bottom fabric.

From the foregoing it will be seen that my invention provides a bed bottom fabric of simple andeconomieal construction, which avoids the useof separate unit-connecting elements, and which may be readily and quickly assembled by simple interhooking and interlinking operations; lt will also be seen that, owing to the disposition of the units in straight axially alined order, longitudinally of the fabric, the tensionstrains are all in longitudinal and transverse directions, thus avoiding diagonal tension which reduces the elasticity of the fabric and also tends to draw in its longitudinal edges in an unsightly manner.

'The particular form of unit herein shown is notofi-the essence the invention so long as the unit is provid with integral endwise connecting means and is capable of direct interlinked connection with laterally adjacent units. 'Inconnection with this latter feature it will be observed that the form of the sides at; the points where the units are laterally interlinked is such as to connect the links rigidly and without permitting any transverse stretch, yield, .or pulling out at thesepoints.

I claim:

1. A bed-bottom fabric of the class de-' scribed, including a plurality of longitudinal rows of diamond-shaped bent wire units disposed in axial alinemepat, the sides of said unit being laterally ofiset relatively to the plane of the fabric at points coincident with he angles formed by the o positely inclined portions of the sides, and aterally adjacent units in the fabric being directly interlinked at such laterally offset points, substantially as described. I

2. A bed-bottom fabric of the class described, including a plurality of longitudinal rows of diamond-sha ed bent wire units terminating in integral hooks and eyes at their opposite ends, respectively, whereby they are connected in axial alinement, the sides of said units being laterally ofiset relatively to the plane of the fabric at points coincident Withthe angles formed by the o positely inclined portions of the sides, and laterally adjacent units in the fabric being directly interlinked at such laterally offset points, substantially as described.

3TH wire mattress composed of a plurality of diamond-shaped links aving oppositelyarranged crimps formed in the upper and under sides of the obtuse angular portions thereof and each link provided at its closed end with a crimp and terminating at its open end in hooks, the oppositely-arranged crimps
